The front() is an inbuilt function in julia which is used to return a tuple consisting of all but the last component of x, where x is the specified tuple.
Syntax: front(x::Tuple)::Tuple Parameters:
  • x::Tuple: Specified tuple.
Returns: It returns a tuple consisting of all but the last component of x, where x is the specified tuple.
Example: Python 
# Julia program to illustrate 
# the use of front() method

# Getting a tuple consisting of
# all but the last component of x, 
# where x is the specified tuple.
println(Base.front((1, 2, 3)))
println(Base.front((2, 4, 6, 8)))
println(Base.front((3, 5)))
Output: 
(1, 2)
(2, 4, 6)
(3, )
The tail() is an inbuilt function in julia which is used to return a tuple consisting of all but the first component of x, where x is the specified tuple.
Syntax: tail(x::Tuple)::Tuple Parameters:
  • x::Tuple: Specified tuple.
Returns: It returns a tuple consisting of all but the first component of x, where x is the specified tuple.
Example: Python 
# Julia program to illustrate 
# the use of tail() method

# Getting a tuple consisting of
# all but the first component of x, 
# where x is the specified tuple.
println(Base.tail((1, 2, 3)))
println(Base.tail((2, 4, 6, 8)))
println(Base.tail((3, 5)))
Output: 
(2, 3)
(4, 6, 8)
(5, )
